You remind me of this guy on a superhero board I visit who keeps insisting that Batman is the highest grossing hero of all time because movies like Suicide Squad, Joker, and Justice League are all 'Batman movies'. Just because something is a film and some people saw it does not make it relevant. In fact, you got me curious enough I'm gonna go do some googling what level of exposure this 'obviously relevant' film of yours apparently has...
Hmmm, well there seems to be only one SW animated film, so that must be the one. Even richer than I thought - it wasn't even made for theatrical release, it was compiled from tv episodes that were originally just going to be aired like the rest of the series. It had negative reception apparently, though a reasonable financial success primarily because of its shoestring budget. It made a grand total of 68 million worldwide (compare that to the much maligned Solo which almost everybody seemed to hate, yet, still made 392 million - the lowest actual Star Wars saga film was RotJ with 475m, and that's in 1980s money) and it also dropped by well over 50% from the first weekend to the second. It even won a razzie. No wonder I never heard of this movie.
You can whine about your standards of film all you want, but you didn't set the scope of this conversation. Peter David did, and his quote is very obviously discussing the Star Wars live action films, not this totally unknown sideshow animation one-off. It is entirely irrelevant.
